Saving and testing your work
You have now finished constructing the secondary windows of the sample investment application, so now is a good time to save and test your work.
Because you still have some more editing to do to the window, save and test your work from the Composition Editor. Be sure to close all the windows you open while testing your application.
When you are done testing, save your image by selecting Save image from the File pull-down menu.
